Function JSObjectGetPropertyForKey

Source 
pub unsafe extern "C" fn JSObjectGetPropertyForKey(
    ctx: JSContextRef,
    object: JSObjectRef,
    propertyKey: JSValueRef,
    exception: *mut JSValueRef,
) -> JSValueRef
Expand description

Gets a property from an object using a JSValueRef as the property key.

  • ctx: The execution context to use.
  • object: The JSObjectRef whose property you want to get.
  • propertyKey: A JSValueRef containing the property key to use when looking up the property.
  • exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

The property’s value if object has the property key, otherwise the undefined value.

This function is the same as performing object[propertyKey] from JavaScript.
